Used Reactor Buying Considerations
When selecting a used reactor, it is important to evaluate both process requirements and equipment condition:
Material of Construction: Stainless steel, glass-lined, or alloy based on chemical compatibility
Capacity & Volume: Match reactor size to batch or continuous production requirements
Pressure & Temperature Ratings: Ensure compatibility with operating conditions
Agitation & Mixing: Evaluate impeller type and mixing capabilities
Heating & Cooling Systems: Jackets, coils, or external heat exchangers
Condition & Maintenance History: Review prior use, repairs, and inspection records
